Not comparing apples with apples. The Wii was pretty much a generation behind everything else and got in on the ground floor with motion controls. The console sold well but the drop off was pretty severe, all the casuals had simply. moved on way before the Wii U launched. Nintendo stopped making on par powerful consoles after the GameCube's poor sales.
At the moment you are simply giving information with no actual context.
I'm not sure a lot of these console sales are ever truly "apple" comparisons when given full context to interpret. Part of PS2's early momentum was for its DVD player inclusion. The ball was rolling before GCN and the new and powerful Xbox hit the market. And of course the titan that would be known as Grand Theft Auto 3, only on PS2.
Wii was virtually sold out for three years, and while hardware sales had lost momentum in its last full year, the machine was still the best selling Home Console of its generation, beating out the PS3 and Xbox 360 (which saw a spike with its own "casual" initiative: Kinect). Much of that expanded audience either jumped to phones, upgraded to core gamer, or just lapsed completely as there was nothing desirable for, say, a Wii Sports fan to play. The Wii U failure can be measured in many different ways, from the largest classic controller to launch for a home console ever (but with a screen in the middle), to the biggest launch software being a sequel to a game that had launched just a few months ago on 3DS (New Super Mario Bros. 2), and looks identical to New Super Mario Bros Wii. This is a momentum business. If you fall off, it becomes harder to get back up.
Where the Wii wanted to simplify the game concepts and bring everyone back to square one, the Wii U appeared more complex, confusing, and not a necessary upgrade to an experience that can already be had on Wii. To put salt on this wound, Ubisoft's break out hit "Just Dance" would continue to sell the best on the original Wii YEARS after the Wii U's launch (despite being available on both). The expanded audience were still there for the pickings, but was not being enticed by the Wii U. Switch has had success with this audience as sales to Mario Party, Switch Sports, Clubhouse Games, and most notably Ring Fit Adventure (not a portable friendly game) all attest to. They ain't gone, and they don't get fed much, but they sure keep things alive for a long long time.
So for the broader discussion earlier about if Nintendo launched a powerful console like the big boys, they'd win, that depends on so many factors, and you have to ask if the traditional console players are even really winning at their game. Studio Closures despite millions of copies sold for games, out of control budgets, less risk, less innovation, more games based on style over substance. The 'Switch' style of hardware is slowly becoming the standard due to its success. But as usual, the execs don't seem to quite understand it, and the focus is on empty shell hardware to put yesteryear products on. The Switch 2 is a home console with the capability of being taken on a plane, to work, or to a friend's house for some tabletop action. Play your way was the Switch motto. The Switch 2 is too large to be a true handheld. It's more akin to a Laptop's convenience and accessibility over a home PC, rather than a phone that can be stored in one's pocket and be used in short rapid bursts.
Anyway, on topic, Star Wars Outlaws is looking pretty passable on the Switch 2. Too bad about the Game Key Card thing though. Hopefully Nintendo addresses that problem with cheaper physical solutions for third parties to take advantage of in the future.
